If two players (or a player and any other entity) are teleported to the
same location in the same tick they will both get added to the other's
destroy queue then have a new entity spawn packet sent. Next tick the
destroy queue will be processed and they will then be invisible to each
other. To prevent this situation we remove the entity from the destroy
queue when sending out a spawn packet for them.

Remove players that cannot see a player from their EntityTrackerEntry and only
send user list updates to players who can see the player they reference.
We know these updates (can) break plugins bypassing Bukkit. They are needed for
smooth updates however. There will be another one right before before 1.1-R1.
This reverts commit 73647864179cbab9f340044e9d33add445fbe774 - "Ignore entity movement packets if distance == 0"
This a commit introduced an intermittent bug which has caused minecart ghosting - they are invisible until you interact with them physically. This is described in leaky bugs:
http://leaky.bukkit.org/issues/547http://leaky.bukkit.org/issues/563
And caused by the fact that normally when loading a chunk, entities fall with gravity before the block data has been loaded, and are sent a zero-distance packet to reset their positions. See Issue #190:
